MIMETIC BIG BANG RIVALRY

Sometimes, just sometimes, quite revealing scientific insights slip into popular culture. I was watching a rerun of an episode of The Big Bang Theory sitcom on Belgian television. More specifically, I found out, I was watching The White Asparagus Triangulation (episode 9, season 2).

The title itself can already be connected to a basic concept of René Girard’s mimetic theory, namely mimetic desire. As it turns out, “triangulation” indeed refers to the triangular nature of human desire (beyond instinctive needs) as described by Girard: the desire of a subject towards a certain object is positively or negatively influenced by mediators or models (click here to watch an example of negatively mediated desire from another popular sitcom, Seinfeld). Humans imitate others in orienting their desires – their desire thus is mimetic.

In the case of this episode from The Big Bang Theory: Sheldon tries to positively influence the desire of Leonard’s new girlfriend, Stephanie. After all, she is the first of Leonard’s dates to meet Sheldon’s high intellectual standards, so Sheldon does everything to increase Stephanie’s desire for Leonard. At some point he tries to persuade the girl next door, Penny, to present herself as a rival/model for Stephanie. Here’s the script for this scene.

Scene: Outside Penny’s door.

Sheldon (Knock, knock, knock) : Penny (knock, knock, knock) Penny.

Penny: What?

Sheldon (Knock, knock, knock) : Penny. Zucchini bread.

Penny: Oh, thank you.

Sheldon: May I come in?

Penny: No.

Sheldon: I see. Apparently my earlier inquiry regarding you and Leonard crossed some sort of line. I apologize.

Penny: Well, thank you.

Sheldon: So, have you and I returned to a social equilibrium?

Penny: Yes.

Sheldon: Great. New topic. Where are you in your menstrual cycle?

Penny: What?

Sheldon: I’ve been doing some research online, and apparently female primates, you know, uh, apes, chimpanzees, you, they find their mate more desirable when he’s being courted by another female. Now, this effect is intensified when the rival female is secreting the pheromones associated with ovulation. Which brings me back to my question, where are you in (Penny slams door). Clearly, I’m 14 days too early.

Several lines of evidence indicate some female competition over mating. First, at Mahale, females sometimes directly interfered in the mating attempts of their rivals by forcing themselves between a copulating pair. In some cases, the aggressive female went on to mate with the male. At Gombe, during a day-long series of attacks by Mitumba females on a fully swollen new immigrant female, the most active attackers were also swollen and their behaviour was interpreted as ‘sexual jealousy’ by the observers. Townsend et al. found that females at Budongo suppressed copulation calls when in the presence of the dominant female, possibly to prevent direct interference in their copulations. Second, females occasionally seem to respond to the sexual swellings of others by swelling themselves. Goodall described an unusual incident in which a dominant, lactating female suddenly appeared with a full swelling a day after a young oestrous female had been followed by many males. Nishida described cases at Mahale in which a female would produce isolated swellings that were not part of her regular cycles when a second oestrous female was present in the group.
